与母体偶氮苯相比，重氮辛（diazocines）（桥连偶氮苯）表现出上级物理性质，例如高转换效率、量子产率，特别是在可见光范围内转换波长。然而，合成以低收率进行，并且衍生物难以制备。我们现在介绍两种杂二氮杂环辛类化合物，它们更容易合成，并且一般的方法也应该提供容易获得的衍生物。此外，这两种化合物都可以用远红光（650 nm）进行转换。可接近性和物理特性使其成为光开关药物和功能材料等应用的理想候选者。
Diazocines, bridged azobenzenes, exhibit superior photophysical properties compared to parent azobenzenes such as high switching efficiencies, quantum yields, and particularly switching wavelengths in the visible range. Synthesis, however, proceeds with low yields, and derivatives are difficult to prepare. We now present two heterodiazocines which are easier to synthesize, and the general procedures should also provide facile access to derivatives. Moreover, both compounds can be switched with light in the far-red (650 nm). Accessibility and photophysical properties make them ideal candidates for applications such as photoswitchable drugs and functional materials.
